President Donald Trump threatened to reduce U.S. troop levels in Germany after tensions with Chancellor Friedrich Merz over the U.S.-Israel conflict with Iran.

Trump said the U.S. is reviewing its military presence and accused Germany of being unhelpful in the war effort.

Merz criticized Washington’s handling of the Iran conflict but maintained that relations with Trump remain stable.

The dispute comes amid broader strain over NATO burden-sharing and the ongoing Middle East conflict, the AP has reported.

The U.S. currently maintains major military bases in Germany, which have long been central to NATO operations.
